GB/T 8628-2001 Textiles-Preparation,marking and measuring of fabric specimens and garments in tests for determination of dimensional change (English Version)
This standard specifies methods for the preparation, marking and measuring of textile fabrics, garmetns and fabric assemblies for use in tests for assessing dimentional change after specified treatment, e.g.washing, dry cleaning, soaking in water and steaming.
The standard is applicable to woven and knitted fabrics and to flat-woven, made-up textile articles. The procedures are not applicable to articles that stretch readily in use, e.g. knitted articles and certain upholstery coverings.

The following standard contains provisions which through reference in this text, constitute provisions of this Standard. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreemetns based on this Standard are encouraged to investigate the possibility of applying the most recent edition of the sandard indicated below.

GB/T 8170-1987 Rules of Rounding off for Numerical Values
3 Principle
Test specimens are selected to represent the bulk of the textile under examination. Pairs of reference points are marked on each specimen and the distance between each pair of reference points is measured before and after specified treatments.
4 Apparatus
4.1 Rule or flexible steeel rule or glass-fibre tape
Marked in millimetres and longer than the greatest dimentsion being measured.
Note 1: The accuracy of glass-fibre tapes should be verified at least every six months.
4.2 Equipmetn for marking precise reference points, such as:
a) indelible ink, for use, if necessary, with a termplate with a measuring grid;
b) fine threads of contrasting colour, sewn into the fabric;
c) heated wire for making small holes (for marking thermoplastics materials);
d) staples (suitable for tests duirng which specimens are not agitated, e.g. for soaking in water).
4.3 Smooth, flat surface, large enough to lay out complete articles.
4.4 Means of producing the standard atmospheres for conditioning and testing textiles.
4.5 Workroom stands, to support garments.
